MOP-HEAD.

SPECIFICATION forming part of Letters Patent No. 414,143, dated October29, 1889.

Application filed January 7, 1889. Serial No- 295,663. (N0 model.)

To all whom it may concern.-

Be it known that I, CHARLES B. CURTIS, a citizen of the United States,residing at Bangor, in the county of Penobscot and State (if Blaine,have invented a new and useful Improvement in Mop-Heads; and I do herebydeclare that the following is afull, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improved mophead for clamping and holding theordinary mog-rag as used for household purposes, and it is illustratedin the accompanying drawings, in which Figure 1 is an isometric view ofmy improved mop-head attached to ahandle and showing the spring-clamp ina closed position. Fig. 2 is asimilar view of myiinproved InOphead,showing a little different shape of the base of the head and thespring-clamp open in position for receiving the mop-rag. Fig. is anisometric view of my improved mop-head with rag inserted and ready foruse.

Similar letters of reference refer to correspondingly like partsthroughout the different figures.

The object of my invention is to produce an improved mop-head that willbe of simple and light construction and easily and quickly operated.

My improved mop-head consists of a D- shaped casting A, having astraight base 6 and a handle-socket 0, cast upon and projecting from thecenter of the portion of the casting opposite the straight side, andinto this socket C is fitted a handle D of sufficient length to suit theperson using the same. The base 6 is preferably cast with a longitudinalgroove extending its entire length, within which are situated shortspurs i, as shown in Fig. 1 of the drawings. A springclamp B is formedby bending spring-wire to conform to the base and ends of the casting Aand turning the remaining portion of the wire into spiral springs 71,until sufficient elasticity is obtained, and then inserting and securingthe ends of the said wire in holes drilled in the eastingA to receivethem. By this arrangement a spring-clamp is formed, the bail portion ofwhich passes down the surface of the ends of the casting A and along thebase or straight side of the latter, the springs it always keeping thebail portion of the springclamp firmly pressed against the D-shapedcasting A. A thumb-piece to raise and operate the spring-clamp Bisformed by either twisting the center portion of the Wire previous tobending into a small loop f, as shown in Fig. 1, or soldering on aseparate loop after the clamp is formed, as shown in Fig. 2 of thedrawings.

My improved mop-head is used in the ordinary way, and the mop-rag isplaced therein by raising the spring-clamp B by means of the thumb-piecef and inserting the mop-rag between the opening and around the base ofthe D-shaped casting. Then by letting go of the spring-clamp B itsprings back in place into position against one side of the rag andpresses the latter into the groove of the cast ing and against the shortspurs therein, thus firmly holding the said mop-rag against any strainand drawing thereon while using. If the D-shaped casting wereconstructed without the groove and spurs above described, the pressureof the spring-clamp B would be sufficient to hold the 1nop-rag in place;but to guard against possible withdrawing of the rag, such as would beoccasioned by'catching one end of the same in slivers in the floor or bystepping on the said rag While using, I think it preferable to providethem with spurs, as shown and above described.

The manner of removing the mop-rag is simply the reverse of insertingthe same, and by raising the spring-clamp and drawing upon one end ofthe rag it is easily and quickly withdrawn.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States, is-

An improved mophead consisting of the D-shaped casting having ahandle-socket pro jecting fromthe portion opposite its straight side,and a spring-wire clamp bent to conform to the shape of the casting andhaving its ends formed in spiral sprin s and rigidly confined to thesaid casting, substantially as shown, and for the purpose described.
